It's impossible to tell what type of wick a heatpipe uses in your
favourite heatsink just by looking at it from the outside. The
heatpipe would need to be cut open to find out the answer to that question....

Let's get right to the point, 3Rsystem's Iceage 120 Boss II heatsink is currently one of the Top 5 heatsinks tested on Frostytech. Key to the success of this Korean-made heatsink on both AMD and Intel synthetic test platforms are five 8mm diameter exposed base heatpipes...

The Scythe Zipang 2 heatsink actually fulfills most of these criteria, essentially silently, thanks to a clever combination of a slow-speed 140mm diameter fan and large cooling surface area. It's not the coolest heatsink Frostytech has ever tested, but it did keep noise levels under 40dB and temperatures to a little over 25C ambient in our 150W synthetic test scenario.

The large top-down heatsink has a jaw dropping weight of 1,225grams, or
1.225kg. That's a lot of weight to hang from a CPU socket, so it goes without
saying that rear motherboard support brackets are mandatory!

DeepCool's Killer Whale heatsink is a top-down cooler built around two critical things. It has a hefty solid copper heat spreader (base) onto which six 6mm diameter heatpipes have been soldered, and a large and potentially very quiet 48mm thick 120mm PWM fan that spins at 1000-1800RPM.

The Scythe Big Shuriken is actually a really small heatsink, well not so much tiny as low profile. From the CPU to the top of the fan, the Big Shuriken measures a scant 57mm tall. That's not a whole lot of space to cram in a heatsink, but somehow Scythe have packed in four 6mm diameter heatpipes, 60 or 70 razor thin aluminum fins and a 120mm fan.

Kingwin's XT-1264 is the first tower-style heatsink to pass through the Frostytech test labs which incorporates asymmetrical U-shaped heatpipes. In other words the heatpipes are not even, rather one length of each vertical heatpipe is 30mm shorter than the opposite.

Standing 157mm tall, the Xigmatek Thors Hammer heatsink tips the scales at 800 grams and has a rather boxy footprint of 120 x 116mm. It accomodates one or two 120mm fans that mount to the fins with special rubber vibration absorbing posts.

One or two 120mm fans can be mounted to either side of the DeepCool Ice Blade Pro, and rubber vibration
absorbing posts are supplied along with extra fan clips. A single 120mm PWM
fan that operates at 900-1500RPM is supplied.

At it's core, Glacialtech have equipped the 136mm tall UFO V51 Silent heatsink with two 1600RPM fans surrounding a large aluminum fin array, and framed in by a plastic casing that acts like a shroud to duct air through it. The heatsink weighs 780grams and is compatible with both Intel socket 775, 1366 and the entire family of AMD socket 939/AM3 processors.

Titan's TTC-NK85TZ Fenrir heatsink
stands 156mm tall, is 124mm wide and accommodates one 120mm fan that spins at 800~2200 RPM. Weighing it at roughly 550grams, the TTC-NK85TZ Fenrir is
compatible with both Intel socket 775, 1366 and the entire family of
AMD socket 939 to AM2+ processors.

Most notebooks have cooling vents on
their bottom which are critical to drawing air into the computer to cool different components. The cooling pad ensures that a steady flow of fresh makes it into the notebook, in turn keeping temperatures in check.
